Looking to deposit -- what site, bonus + rakebacks/rake rates?

[metsmaniac823]

For a relative beginner, what would be the best site to try first? I lost two $50 buy-ins a year ago playing some NL tables, one at PartyPoker, the other at PokerStars, (really) slightly out of my element at the time. I'm planning to put in $100 to play some micro-limit games. What site would you guys recommend? I plan to use this $100 as the bankroll to build up, is this too small even for the low limits (such as .05/.10)?

Also, I'm starting to look into these rakeback sites, I'm not really familiar with the concept though. You sign up through them and they give you money? Where exactly do they get their money, and how much do they take out of your money? A brief explanation would be very helpful, thanks.

Final question: when should I be investing in PokerTracker? I am very interested in picking it up, but at this point, would it be worth it? Again, thanks to everyone who helps; hope the new year is prosperous for all of us. Most of us. Okay, fine, just me. [img]/images/graemlins/laugh.gif[/img]
